The absence of a clear influence of the responses modified by new connections created by LTP on the development of these connections casts doubt on an essential role of LTP in learning and memory formation without any association with reinforcement. The evidence for the involvement of the monoaminergic systems in synaptic potentiation in the cerebral cortex during learning is adduced, and their role in reinforcement system function is discussed.
